A. Job Set-Up
(1) Pressurize the Blue hydraulic system with the electric pump (Ref. AMM TASK 29-10-00-863-003).
B. Test
(1) Do the BITE test of the EFCS (Ground Scanning) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
ELAC 2 OR WIRING FROM B HYD PRESS SW1
or
ELAC 2 OR WIRING FROM B HYD PRESS SW2
- replace the ELAC-2 (2CE2), (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
